I think your misstake is that you assume that only LI-teams want passing and OD on bigs. Actually when you are going to build an outside team and you are aware that you are going with an offense that is disadvantaged by the engine, you will want as much defense and flow as you can get on ALL positions. LI-teams can do without that easier, because, like Robard said, they will just overpower their opponent with their pure offensive force.
It does seem odd to advertise this in advance as a way to stop LI dominance, when I think it would be clear to anyone that an outside offence requires outside skills on big men. I think what we'll see, as with other changes in the past that didn't quite work as intended, is that the BBs will stop saying it was to stop LI dominace and was just brought in to make people pay for secondaries on all players.
